Chinese scientists claim to have built a quantum computer that is able to perform certain computations nearly 100 trillion times faster than the world’s most advanced supercomputer, representing the first milestone in the country’s efforts to develop the technology.
The researchers have built a quantum computer prototype that is able to detect up to 76 photons through Gaussian boson sampling, a standard simulation algorithm, the state-run Xinhua news agency said, citing research published in Science magazine. That’s exponentially faster than existing supercomputers.
The breakthrough represents a quantum computational advantage, also known as quantum supremacy, in which no traditional computer can perform the same task in a reasonable amount of time and is unlikely to be overturned by algorithmic or hardware improvements, according to the research.
While still in its infancy, quantum computing is seen as the key to radically improving the processing speed and power of computers, enabling them to simulate large systems and drive advances in physics, chemistry and other fields. Chinese researchers are competing against major U.S. corporations from Alphabet Inc.’s Google to Amazon.com Inc. and Microsoft Corp. for a lead in the technology, which has become yet another front in the U.S.-China tech race.
Google said last year it has built a computer that could perform a computation in 200 seconds that would take the fastest supercomputers about 10,000 years, reaching quantum supremacy. The Chinese researchers claim their new prototype is able to process 10 billion times faster than Google’s prototype, according to the Xinhua report.

More Chinese “information”. Yeah, that is the ticket.

So the ChiComs claim to have built a quantum computer. Take yer pick.
A. The ChiComs are lying (again).
B. The ChiComs are using stolen technology (again).
C. Both A and B.
Having worked with Chinese engineers, I can say this. The Chinese are very good at execution, but lack any outside of the box thinking. They are trained to pass test, not to come up with innovation. Any technology they acquire comes from elsewhere.
Yeah, they just figured out COVID-19 came from China.
Good work boys...
So... who did they steal it from this time? What was the Clinton cut?
A headline befitting the Babylon Bee!
NO ONE believes this.
Meh.
THe only metric of note is how many ballots can it create per second.

They built a device to do one particular thing. It cannot do anything else. It cannot be modified to solve any mathematical problems.
More details:
A team in China built a boson sampling device using laser pulses sent into a maze of 300 beam splitters and 75 mirrors.
If you shoot many photons through a sequence of beam splitters many times in a row, patterns begin to emerge in the paths of the photons that are extraordinarily difficult to simulate or predict with classical computers. Finding possible sets of photon paths in this set-up is called boson sampling, and a boson sampling device is a type of quantum computer, albeit one with a very narrow purpose.
A perfect boson sampler would have a fidelity of 1 over many trials, meaning that it completely matches up with theoretical predictions. Jiuzhang had a fidelity of 0.99.

My Harvey is bigger than your Harvey!
I’ll take A for a million dollars or if it isn’t A then I’ll take B for 10 Million.
Yep. Can’t say it any better than that.
Wow imagine what this does to the next US elections in 2022:-)
How can they count that fast?
Something I’ve never quite gotten on quantum computing - it may be massively faster, but it would seem like the underlying concept would guarantee the outcome could not be 100% accurate.
A breakthrough for criminals and crimes against humanity.
About as useful to man as radioactive waste.
I have similar questions about these sorts of headlines:
Light From Beginning Of Time That's 600 TRILLION Times Brighter Than Sun Reaches Earth
Pfffft! That's nothing. Wait until they get to 100 Gazillion times faster!
